This report describes a method for a telepresence system in which a cyclic-motion of a moving object is reproduced from video sequences taken from different viewpoints. The proposed method is constructed of two processes: (1) synthesis of naturally looping video for each viewpoint, (2) connection of frames between adjacent viewpoints.

In this paper, we propose an object extracting method in wide outdoor space, which is based on an object tracking method using particle filter in 3D-space. The likelihood of each particle is calculated by projecting it to every viewpoint and summing up all the likelihoods. Experimental results show that the integration of multi-viewpoint is useful for extracting object regions in wide outdoor space.

This paper propose a method of complimenting viewpoint by using circle-position camera's multi-view images and by block matching method. These circle-position cameras direct to the center of the circle, and complimented viewpoint also direct to the circle. When block matching, we use information of camera position to narrow the range of search.

In our approach, we use several images focused on different depths taken from different viewpoints and we can generate an all-in-focus intermediate view from these images. This approach does not require estimations of feature correspondence. Reporting the comparison of the results of three layer three aspects and four layer four aspects, we examine the effect of expanding them to multilayer multi aspect. We especially indicate a causal connection between the distance between cameras and focus blurs

Adaptive interpolation filter (AIF) technology is the efficient coding tool to improve the coding performance. To reduce the complexity of AIF algorithm, low complexity approaches were proposed. However, those schemes resulted in coding performance degradation due to inaccurate calculation of filter coefficients. To overcome this problem, we propose a selective interpolation filter approach that selects an appropriate coefficient set among several pre-defined representative candidates.

This paper presents a novel approach to track human motion with a monocular video based on particle filter. To deal with the high dimensional freedoms in human pose, a low dimensional latent space, e.g. Gaussian Process Dynamical Model (GPDM), is a typical solution. In this paper, we extend the GPDM model into a graph structure to better express the diverse dynamics in human motion, where multiple latent spaces are constructed and connected with each other.
